So, I don't have to post you a data lead and power lead?

Just after midnight on the morning of 01-01-2000 I turned my BBC
Master on and the PSU went <pfut>. My wife was convinced it was
the Millennium Bug!

Annoyingly, every AForm program I've tried doesn't like having a
hard drive present. I've ended up having to *CONFIG. FLOPPY and
then run it from the network.
 
Even then, it doesn't like being run from a non-ADFS filing
system. I have to *LOAD AForm, *FADFS, CALL <whatever>.
 
One of my tasks I have set myself is to write a replacement *AForm
program - or at least dig though the ones I have and try and work
out what it doesn't like hard drives being around.

You should be able to initialise drive 1 as another 512M.
